# Early Stage 1, mathematics – Unit 05

Develop students' understanding of how new shapes can be made from existing shapes by exploring the attributes of shapes, and by using combination and partitioning in this two-week unit.

## Syllabus

Syllabus outcomes and content descriptors from Mathematics K–10 Syllabus (2022) © NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales, 2024.

In this unit – 'New shapes can be made by joining (combining) or partitioning (breaking apart) existing shapes', students will learn that:

• two-dimensional (2D) shapes can be made by joining (combining) and breaking apart (partitioning) existing shapes
• shapes have attributes that are necessary for classification as that shape (features of triangles, circles, squares, rectangles)
• necessary attributes are called features
• shapes and objects can be halved in different ways
• new shapes can be created by adding or removing sides
• numbers, like shapes, have smaller numbers hiding inside of them (numbers 0 to 10).

### Syllabus focus and content groups
